Be advised that WRF ( Winchester Rim Fire ) is not the same as 22 Winchester magnum. Good news, CCI has started producing the 22 WRF. If a 22 cartridge is a very loose fit then it takes the 22 WRF. If you shoot a 22 Short, Long, or Long Rifle in a 22 WRF chamber the case will rupture and may spit gas and unburned powder at you. The 22 WRF is a thicker or fatter case than the normal RF, but shorter than the 22 Winchester Magnum. Now if you're not confused, then you having been paying attention
, Any questions, post back.
